B is the spindle upon which a'contiuuous roll of paper to vbe'made into lbags is placed, from whence it is carried forward over and under Athe rollers C C` Cl', the latter being made ad'- justable by means of aset-screw. The spindle B is supported by standards 4fixed to a plate., a, which is held` on the sides of .the frame x by set-.screws iu slotsAto admit of a transl verse-movementadj ustment, which adjustment 1s effected by a screw,` a', workinginto a tired nut in the side of Ithe frame A, underneath the! plate, having acrank-handle, b, fixed in a flange in the end of said` plate a,'so that.

The wheel c, revolving in' a trough, c", iu which the vpaste is deposited, thus takes the paste from thetrough aud'applies it tothe edge of the j under side of the paper, and 4is-zuljustable by means cfa screw-to any sized bag to be made, the paper being held tofsaid wheel c pressure-wheel, d, revolving on theupper side l thereof, as seen in Fig. 1. The paper, with the paste applied, `is then carried uuder roller Cf, thence over G,- and'uuder the revolving forinf ing-ba cular armature to a horizontal bar, supported ,on standards E, as shown in Fig. 1 This revolving ball breaks down the paper, and peculiarly adapts it for entrance under the former F.

, The former F is constructed in themauner usual'in machines of this'nature, andis re v movable/,and adjustable by meansof a setscrew, working into a plate fastened to the horizontal bar held by the standards F',F,

'with guides efeupon each side, which are `ad- Ais the frame,lmade.o f any suitable form .and materiah'in the sides of whichv are placed by a small l D. This .ball'is held in positionrby I .being rigidly fastened bymeans of a semicirinstable horizontally in reference to the width oi' tinJ bags to he made, and vertically in ret'- erenee lo the lhicliness of paper used. The ringer keeps down the pasted edge of the paper from contact with-the other edge until they are pressed together by the pressing-rollers H H in advance. lhcnec the now-formed tube is carried between the draft-rollers I l to the cultingltnives ll l. These draft-rollers are driven by gearing, operated upon by the driving-wheel G, having a beveled gear, g, at the end oi' its shaft, which works into the beveled wheel y" on the longitudinal shaft G', placed upon the top of the tableA, having beveled gearing y, to Vwork the rollers I l, a beveled pinion, g2, which works into a beveled gear, gl, on the end of a short shaft` K', which gear y* can be changed to make the cutoff blade ll work faster or slower to suit the size of the bag to be iliade. The other end of this shaft has a cog-wheel, k', which works into another cog-wheel, K, on a transverse horizontal shaft, h, supported4 by standards h h on the sides of the frame A, said horizontal shaft h having on it a disk, lr", to correspond with the cog-wheel l on the other side of the central line of thel machine. From the inside of the cog-wheel lc` and correspondingdisk k" are pins yi i, which, by the revolution of the said shaft h, force down the rods l l on the heads i i of the cut-olf blade or brake, which work in appropriate guides, i i, attached to a plate,

i l" ,'fastened to the under side of the frame A,- :througb which plate l. also are holes for the l, rods above mentioned, the rods being connected below this plate by a horizontal bar, l',

which serves as a rest fortho ends of the springs m m, the operation of which will be more fully explained hereafter'. z 0u this plate l" also is a standard, ln, Fig. 1having a horizontal pin, af, which serves the purpose of turning an arm, n, on the end of the shaft n of Athe cut-oli' blade. On the inside of the pinion K', Figs. 3 and 2, isa wrist, from which a connecting-har, o, depends, and which is attached to a bell-crank lever onA a horizontal shaft, p, vunder the table, supported in brackets from the frame A, which bell-crank levers are connected to crooked lever-bars L L, which move theshaft r horizontally in guides at .bothg ends of it by means of hollow, square journal-boxes, which boxes permit the rotary motion of the shaft r, on one end of which vis a crank, r', the pin r of which works in a A cam-shaped groove, fr, which serves the purpose of turning the paste-knife and end-folder1l from the pastor l, where it` has been supplied with paste bythe operation of the anachine, to `appl)7 it to the end of the bag,

i and at the same time force it between the .pressure-rollers It It, which rollers, by their action, carry the bag from the machine. Near the end of the horizontal longitudinal shaft G is a beveled gear, i which works into the gear of the roller N, onthe other end of which is a cog-wheel, n, which works into a corresponding cog-wheel, n, of the roller N immediately vunder it. Around each of these rollers N N is an endless band, 0 O, which may be made of cloth or other suitable material, which also works around the smaller rollers M M, having between the rollers M and N a' standard, .s-,on each side, iii which standards are two rollers, t t, working in the ends of levers s s', pivoted in said standards, the lower ends of which levers having setscrews t t', working in concentric slots s s in the standard s s, the purpose of which rollers t t is to tighten or bring together these endlessbands O O with friction suieient to draw along the tube which has been severed by the cut-off blade I immediately in the rear, and at the same time to hold the tube while the cut-0E 'blade is operatin g.

To the end of the arm n, coming from the shaft of the cut-o" blade l', is attached the end of a spiral spring, u, Fig. 2, the other end being suitably attached to the under side of the table A', the operation of which will be hereafter more fully explained. v

In the revolution of the transverse horizontal 'shafth, the pins i strike the top of the rods l l, attached to the cut-off blade l', which forces them down, taking with them the cutoi' blade 1', when the rods, under pressure `from the pins, are released in a moment from the pressure ineited' during the revolution of the shaft h, and the cut-off bladeJ is again forced quickly up by means of the two springs m m, while the blade I receives a cutting motion by the operation of the spiral spring u, heretofore described, and is also thrown forward o ut of the way of the advancing tube.

The adjustable guide S, for the formation of ythe bottom of the bag, is fastened to the frame A by' two screws,1and 2, movable in slots in the brackets 3 and 4, which brackets have also vertical slots, in which two screws, 5 5, work, they being fastened to the guide Sv, which arrangement. gives a horizontal movement to the brackets 3 and 4', and al vertical adjustment of the guide S. i The pressing-rollers 'R R may be moved closer or farther apart by means of set-screws w 4r, placed in the center of the cross-bars supporting the standards.

, Upon the ends of the rollers N and R are pulleys, by which motion is communicated, in thcfusual way, to the pressing-rollers R R.

The vpasting-roller 1 is driven by a rollei, Q. placed under the frame A, in connection with a pulley on the end of the ylongitudinal shaft G. (Not seen in the drawing.)
